How does a presynaptic neuron know just how much of a certain neurotransmitter (NT) it has released into the synapse?
Llana [10]

Answer:

A presynaptic neuron knows when and how much of a certain neurotransmitter it has to release into the synapse by the frequency of the action potential.

Explanation:

Two nuerons connect to each other through synapse. When an action potential, or nerve impulse, arrives at the axon terminal, it activates voltage-gated calcium channels in the cell membrane, then the calcium which is present in hi highconcentration outside the neuron than inside, rushes into the cell. The Calcium then allows synaptic vesicles to fuse with the axon terminal membrane, releasing neurotransmitter into the synaptic cleft.

The nuerotransmitter than binds to the receptors at the post-synaptic cleft and causes the opening or closing of the channels, hence, depolarizing or hyperpolarizing the cells.This can produce a change in the membrane potential—voltage across the membrane of the receiving cell.

. According to the concept of entropy, what will likely happen to most molecules over time? (Points : 3) . -They will break down
emmasim [6.3K]
The correct answer is this: THEY WILL BREAK DOWN.
In chemistry, entropy is defined as the degree of disorderliness or randomness of a system. Entropy has to do with the second law of thermodynamic, which relates to how energy spread out. The entropy of a system can be positive or negative depending on the direction of flow of energy. In positive entropy, the degree of disorderliness increases while in negative entropy the degree of randomness decreases. A positive entropy will always leads to the breakdown of the affected molecules.
